PRINTING-GAGE.

Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed July 23, 1906. Serial No. 327,274.

To all whom it may concern.-

Be it known that we, INILLIAM DUKE, Sr., and WILLIAM DUKE, Jr, citizensof the United States, residing in the city and county of Philadelphia,State of Pennsylvania, have invented a new and useful Printing-Gage, ofwhich the following is a specification.

Our invention consists of an improvement in agage for setting sheets tobe printed true and uniform on the platen of the press, the novelfeatures of the same being hereinafter described, and pointed out" inthe claims.

Figure 1 represents a perspective view of a gage for a printing-pressembodying our invention. Fig. 2 represents a top or plan view thereof.Fig. 3 represents a longitudi- Fig; 4 represents a similar section online y y, Fig. 2. Fig. 5 represents a similar section 011 line 2 2',Fig. 2. Fig. 6' represents a section similar to that shown in Fig. 4with the parts in different positions. Fig. 7 represents a horizontalsection of a portion of the gage. Fig. 8 represents a top or plan viewof the gage, on a reduced scale, shown in operative position on theplaten of a printing-press.

Similar letters of reference indicate corre sponding parts in thefigures.

Referring to the drawings, A designates a base on which are mountedpairs of parallel cylinders B B and C C and the cylinders D D, one ofthe latter being interposed between the pairs of cylinders B and theother being interposed between the pairs of cylinders C. In eachcylinder B C is the telescopic section E, with which is connected theplunger F.

Secured to the forward ends of the plunger of each pair of cylinders Bis the cross-bar G, and secured to the plunger of each pair of cylindersC is the cross-bar H, it being noticed that said cross-bars G and II areon opposite sides of the center of the gage.

Projecting forwardly and outwardly from what may be termed the front ofthe gage are the prongs or fingers J, whichare somewhat sharpened orpointed, so as to readily enter the tympan-sheet, it being noticed thatthe bars G and H are recessed, as at K,

whereby said bars in their motions may readily slide over said fingers.

In the cylinders D are the telescopic sections or plugs L, from whichextend the plungers or rods M, which pass through said cylinders D,within which are the springs M, which bear against said sections L andthe ends of said cylinders as abutments, said springs thus formingresilient resistances for said sections when the toggle-levers arelowered, permitting, however, said sections and the plungers M tocontinue their motions when the registering-bars H are seated in adirection the opposite to said bars, said springs afterward assisting torestore the movable parts to their normal positions.

P designates springs which are fitted on the plungers F and bear attheir ends against the telescopic sections E, as shown, and the end ofthe cylinders B C, respectively. On the outer ends of the plungers F arenuts Q, which are adapted to bear against the telescopic sections E inorder to adjust the position of the relative parts and the tension ofthe springs P. On the outer ends of the plungers M are nuts N, which areadapted to bear against the adjacent ends of the cylinder D in order toadjust the position of the relative p arts and the tension of thesprings M.

R designates toggle-levers the limbs of of, between the respectivecylinders B C, is

the elbow-lever S, the upper limb of which rises above the top of thelevers R. Connected with the limbs of said lever S at the joint thereofis the spring T, the object of which is to hold the upper limb elevatedand salient, as most clearly shown in Figs. 3 and 5.

The operation is as follows: When the reglet or other proper part of thepress is lowered, it bears against the upper limb of the lever S as theprimary pressure occurs, thus lowering said lever and placing it incontact with the paper for primarily holding the same. As the regletcontinues its descent it bears against the joint or top portion of thetoggle-levers R as the secondary pressure .device, thus straighteningsaid levers, and consequently advancing the bars G and H, the lattercontacting sidewise with the edge of 'the paper, bearing against thesame, sothat as the paper moves under the contact part of the lever S itis placed true on the tympansheet, it being noticed that the bars G andH, whose motions in the present case, as shown ICC r Consequently saidsections L and the plungers M move to the left. In the motions of theplungers they compress the springs M, whereby the latter exert apressure against the connected parts to assist in retaining them in thepositions they now assume, while they also provide a resilientresistance to said plungers, which avoid strain on and breakage of saidparts as the latter are operated. When the reglet rises, it releases thetoggle-levers and elbow-lever S,' when the springs M, P, and T serve toreturn the bars G and H and elbow-lever S to their normal positions.

' Having thus described our invention, what we claim as new, and desireto secure by Letters Patent, is i 1. In a gage of the character stated,a primary pressure device, a secondary pressure device, and depressiblemeans for actuating each of the pressure devices one after the other bydirect engagement therewith of a movable member of a press.

2. In a gage of the character stated, a pri mary pressure device, asecondary pressure device, depressible means for actuating each of thepressure devices one after the other by direct engagement therewith of amovable member of a press, and means for returning said devices to theirnormal positions.

3. In a gage of the character stated, a registering-bar, a toggle-leverhaving one limb connected therewith with its joint in position to bedirectly engaged by a movable member of a press, members telescopicallyfitted to each other, the movable member thereof being connected withsaid limb, means for returning said movable member and consequently saidbar to its normal position, a primary pressure device, and an actuatingmember therefor independent of said toggle-lever.

4. In a gage of the character stated, a primary pressure device, aregistering-bar independent thereof, a toggle-lever connected with saidbar, a guided member connected with said lever, and means independent ofthe said pressure device for guiding said bar.

5. In a gage of the character stated, a primary pressure device, aregistering-bar independent thereof, a toggle-lever connected with saidbar, a guided member connected with said lever, means independent of thesaid pressure device for guiding said bar, and means for returmng saldlever and consequently said bar to normal positions.

6. In a gage of the character stated, a registering-bar, a leverconnected therewith, a movable piece with which a limb of said lever isconnected, a tubular guide for said piece and a plunger on said piece,said plunger being adapted to pass freely through an end of said guide.

7. In a gage of the character stated, a registering-bar, a leverconnected therewith, and disposed in position to be directly engaged bya movable member of a press, means for guiding said bar and lever, anendwise-compressible spring for returning said lever to its normalposition, means for adjusting the ten- -sion of said spring and meanspermitting movement of the lever after the movement of the bar ceases.

8. In a gage of the character stated, a registering-bar, a toggle-leverpivotally connected therewith and disposed in position to be directlyengaged by a movable member of a press, a movable piece attached to alimb of said lever and a guide for said piece.

9. In a gage of the character stated, a registering-bar, a toggle-leverpivotally connectedtherewith and disposed in position to be directlyengaged by a movable member of a press, members telescopically fitted toeach other, one limb of said lever being attached to one of saidmembers, a spring engaging said members to return said lever and bar totheir normal positions.

10. In a gage of the character stated, a primary side pressure deviceand a secondary pressure device parallel therewith and arranged to bedirectly engaged by a movable member of a press after said member hasengaged and actuated the primary side pressure device, the latterindependent of and on the side of said primary pressure device.

11. In a gage of the character stated, a registering-bar, a toggle-leverconnected therewith, means for operating said lever to lower the same, amovable piece with which a limb of said lever is connected, a guide forsaid piece, a resilient resistance device for said piece and an abutmentfor said device whereby when said bar is moved to operative position,said piece and. connected parts are adapted to continue their motions inthe direction opposite to that of said bar.

12. In a gage of the character stated, a primary pressure device, asecondary pressure device independent thereof, and independent actuatingmeans for said devices arranged in different vertical planes to beindependently directly engaged in succession by a movable member of apress.
